This ongoing project aims to examine the relationship between using an active workstation (engaging in light-intensity physical activity) and stress responses. We implemented the Trier Social Stress Task on different types of workstations and assessed physiological and psychological stress responses. This study will contribute to the theoretical framework of activation of HPA axis during physical activity, and provide practical suggestions for people who have a stressful and sedentary job.
This is a between-subject experiment conducted in the laboratory setting (N = 242). We found that using a treadmill desk for about 32 minutes significantly improved participants' arousal and pleasantness compared to sitting, without compromising reading comprehension ability and creativity. Additionally, participants using the treadmill desk enjoyed the tasks the most, while participants using the standing desk enjoyed the tasks the least. Greenery in the room or not did not lead to any changes in cognitive performance, mood, and enjoyment in this one-time intervention. (Manuscript under preparation)

This is an online randomized controlled trial (N = 2829). Participants viewed a menu from Wendy’s with randomized menu labels (having calorie labels or not, having sodium warnings or not, having “natural” labels or not), completed a hypothetical order, and answered questions assessing health literacy. We found that individuals with high health literacy generally had a lower total calorie and sodium while those with low health literacy had the opposite pattern. Interestingly, the menu labels were only effective for individuals with moderate health literacy—this group showed a significant reduction in total calories and sodium in their hypothetical orders under several intervention conditions compared to the control group.

We are analyzing the data collected in 2017 on adolescents’ eating behaviors and physical activity. The primary analysis showed that all participants met the Physical Activity Guidelines for Americans, but only 8.6% had a “healthy diet,” according to the Healthy Eating Index.

This study investigated how walking behaviors were different in the real world and in virtual reality. It serves as a feasibility test for future research on studying street walkability in virtual reality.

This study assessed the effects of brief dissonance-based social media interventions on eating behaviors among Chilean women and their children. Primary analysis shows that this brief intervention did not yield behavioral changes.

This study evaluated the impact of a One Health focused training program on students’ perceived value, comfort, and ability when working in interdisciplinary teams. Perceived comfort and value significantly increased from before to after the program.
